Hirayama is a Tokyo-based zine artist, and from the timing and the decor, I would guess this was made as part of Hon to Sakuhin (Books and Works), his just-closed exhibition at Pantaloon, a design/event firm in Osaka. The show traveled the Japanese art book circuit, starting out at Edition Nord and Utrecht in Tokyo.

The un-Google Translate-able single jpg website for the Pantaloon show mentions a transformed cafe, video, and "movie-like sequences," but has no mention of silent Mylar spirits.
